In addition to its fundamental duty of fluid storage, a well-designed reservoir also dissipates heat, provides time for contamination to fall out of the fluid, and for air bubbles to rise to the surface and dissipate. (A traditional, non-application specific, rule of thumb for tank sized to handle all these functions well is 3 to 5 times "Q", where "Q" equals the pump discharge rate.)

Faced with conflicting demands, how can hydraulic system designers keep reservoirs working effectively while shrinking the overall system footprint? On solution to consider are aluminum hydraulic reservoirs. Widely used and popular throughout Europe, they are increasingly being adopted by companies across North American. A primary benefit of aluminum reservoirs is the fact that they have a higher heat dissipation than steel. In some cases, this additional heat dissipation may even be enough to eliminate an external heat exchanger from a system (saving overall space, initial system procurement cost, and indefinite system operational run time costs). Second to heat dissipation, aluminum reservoirs reduce lifetime maintenance costs as they do not need to be painted and repainted (as steel tanks may rusts).Third, within a given size range, aluminum reservoirs nest within each other, allowing for reduced floor space demands when holding inventory.

Bonus New Product Update: While Lovejoy has long offered 6 standard sizes of aluminum reservoirs through 70 liters (18.5 gallons), Lovejoy's sister company in Germany (R+L Hydraulics) recently released a 130 liter reservoir with an effective volume of 123 liters. This product is readily available from Lovejoy and Lovejoy authorized distributors in the North American market. As of the release of this blog post, literature for this latest largest size is current only available for it on the R+L website, which can be found by clicking here.
